While this item certainly isn’t a woodworking power tool, Ryobi’s Power Usage Meter, released late in 2009, can help you become a wiser electricity consumer in your home or shop. The meter simply plugs into an outlet, and its onboard grounded plug will then accept the plug of most 15-amp home appliances, including televisions, stereos, computers, microwaves, cell phone chargers and other household or consumer electronics. It can evaluate the daily, weekly, monthly and yearly power usage and cost of whatever you have plugged into it. Ryobi estimates the meter to be accurate to within +/- 3%.
Finally, here’s a way to know exactly where your utility dollars are being spent—quickly and easily. The Ryobi Power Usage Meter has a street price of $24.97, and you can purchase it at your local Home Depot store.
